IMPROVEMENT IN PAPER-FOLDING MACHINES.

l' Tha Schedule referred to in these Letters Patent and making part of vthe uma.

.'lo all whom it may concern:

Be it known that I, Crans Gnalunnns, Jr., forlnerly ot' Kennett- Square, Pennsylvania, now ol' Ihila delphia, Pennsylvania, have-.invented a Machine for Folding lapcrg and I du hercbydeclare the following to be a full and colrect description-of the same, reference bcillg had to thc. accompanying drawings, ill which- I Figure 1 represents tl e machine in perspective, with halt' ot' the cover or leerling-table Z removed.

Figure 4 represents the mechanism which carries out, presents, and retains the paper ready for the opel'aton of the next folding mechanism..

Figllre 5 sllows th'e shape 'of the cam for operating the register-pins I 1'. l

Figure 6 shows the shape of the cam for operating the blade E.

Figure 7 shows the position of the several cams-oa the main shaft', with respect to eachother.

- Figure 8 shows the cam which operates the blades Figure 9 shows the maln'ler of operating the'hlades F and H, by means ot' thecl'lm 8, giving the same amount of throw to each. l

This invention is all improvement in machinery for folding paper for books, and relates- First, to the adaptation of register-pills to present the printed sheets of paper to the folding mechanism by being introduced into holes previously made in the `v paper when printed, said holes being made ill the linef. of the first fold.

Second,..to the manner of adjusting said registerpins to the holes in the paper, and adjust-ing thenl'so as to present the-printed 'Sheets of papel' in proper. position to receive their filet fold hy t-h'e folding mech! anlsln. y l l 1 Third, to the manner of present-ing the once folded sheet ot' palper to the second folding mechanism ill pnlper position to rece'verthe second fold.-

Fourth, to 'the n lanuer of arresting and retaining the folded sheet preparatory to receiving additional retaining the paper irl-position for'folding.

Sixth, to the ypeculiar movement of the folding, blades between die rollers. l Y

Seventh, to the manner of delivering 4the folded sheets from the machine.

justed'and retaine-dillits position-l' acl-ew, (see igs. 2 and 3.)' The register-pin 1' has' lntervcllillg beweer itnd. the bar K the block lll, llt-which the legist'erfpin, l .slides in aY V, and the said block M sllde's in a lV ow Eight-h, to the 'mode of arlesting at will the motion of cert-ain parts ot' the folding'nlechanism, to allow time for registering the shlct. In order to enable othersl to make and -u'se my in volition, I proceed operation.

In t-lle drawings isV represented a frame of any sll'itahlematerialill lvhiclr the vhole of the machinery is supported, as clearly represcnted in fig. 1.

To the upper projecting arms of the fralne,and to thc. left-hand side of the machinery, is attached the table Y,lslighlly inclined ton'rl'd t-lle maohine'tor hold'A ing the bank ot' unfolded jlleets. Across, near the center, and at the top of the frau'le, are located the lrst tll'd-ilding-rollers A A', running. :in suitable hennng's, secned ce1-the sido pieces-otltlleli lllllt.-

At rightangles to, and below the rollers 'A A', are located the rollers B B', having their bearing at one end under the rollers A A', and secured to the eentral cross-bar, and at the other end to the under side -of the near upper end :'ail of the framing, as clearly shown ill fig. 1. l

'The distance between the top surface of the rollers B B' and the lower surface of the rollers A A' should be such as Ato allow-tile lille passage of a folded sheet of papel', when carried out horizontally from the rollels A A', so as not to come in contact -with the sllr face of the rollers B B.

-In like manner are arranged the rollers C C' below the rollers l. B', apd D D below the rollers C C', each having appropriate bearings in the cross-pieces of the framing, as shown ill fig. 1. y

Between lthe rollers A A', alld within grooves 'in them, the register-pins I I' project upward, their shouldels coming level with the table Z Z', and are secured to the lla-r K bl means ofa V--O and-adjusting screw. Their point-s project slightly above the table Z Z',and are dressed slightly conical round and smooth for readily entering the holes iuthe paper,

(see figs. 2 and 3.)- 1

The har K slides in a V- 011. the lever L, and is adthe b ar K, and is alljlltdvnnd 'retained bythe screw 1. i

'.llle screws'l and block M and the lever Il. A

The lelfer L is secured t0 lts shaft, winch has suit- Aable bearings in boxes sccllred'to the main flame, (see to desd'ibe its construct-ion and the adjusting 2 turn loosely in the end-of theA bar K, between shoulders, and are tappcdinto the -ibiding-biiuie F,

along between them lllxteuding,r from a rock-shaft, near to the shaft of the lever li, and parallel thereto, and about level with the center of the rollers A (sce figs. l and 2,) is the bent ariu 14, which carries' the first folding-blade 2. This arin is of such length as to allow the edge ofthe folding-blade to coule between tht` rollers A A'.

1t derives motion freni the cam l through the friction-rollev aud arin 13, as clearly shown in fig. 2.

The bent alni lll; has a prnie'ctiou, 1S, on it', which extends downward, and within the range of the l'op of the lever 19, said lever extending up from the shaft 20, which works in suit-able hearings in the lower end rails ofthe framing.

The shaft 2() has attached to the projecting eiid, atthe. rear end of the machine, a treadle, 2l, which treadle is held Jip, and the le\er 10 hack, to clear the path ofthe projection 18, b v means ol'a spring coiled around the shalt.

The blade E has two nett-hes enlont nm'msite to the register-pins l l', of suitable. width to allow of the adjustment ofthe pins, and of'suit-able depth to allow the edge el' the blade to come on a line with the shoulders of the register-pin.

- This blade has also a. nnrnlrer ofueedle points, l 1*, secured to it by means ol' lsniall grooves cnt in the. blade, and of clips and screws, These points are allowed to project below the edge of the blade, so as to penetrate the paper before thel edge of the blade comesin contact therewith, ihr reasons which will be hereafter explained.

To the radiating arnis Elfi, (see figs. 1,2,and 9,) from a shaft ou the lelthaud side of the machine, working in suitable bearings, is attached the second foldiug-blade 1 in such inanucr that its edge shall come between the rollers B'.

To the edge o!"- this-.blade are attached the tine points 1 1', as described for the blade E; and in like inanncr the'hlades G Aand ll are attached to their arms and shafts 17 and 27, so as to come between the rollers C (1" and l) 1)', and are provided with pointsl 1, as before described. l

Around the roller A', down between' the rollers A and A', horizontally to the adjustable tapepulley 1t, and back to the roller A, pass a, series of endless tapes, T, (see figs. 1 and 2,) in such manner as to convey a folded sheet of paper issuing from the rollers A audA', horizontally above the rollers B andB', and under the knife 1", when it is up. l

Between the tapes T T, and slightly below 'their upper surface, and parallel therewith, are located the bars Q Q Q Q, (see figs. 1, 2, and 4.)

Sliding on these bals Q, and at right angles therete, is the stop-bar S, which' projects above the surface of lthe said bars, and across th'e'path of the sheet of 'paper moving ou the tapes T and the bars Q, and has notches eut out teclear' the bars Q -t`o pass through, audan arch spring over the as clearly sluwn in fig. 4.

The said stop-bar may be secured in any desired position on the bars Q, by means of .the setscrews 4 and 4'.

To .the under 4side of the table Z ale secured bars Q', (see tig. 2,) whose under sides' are slightly above the top surfaceof thc tapes T, and belowtbe edge of the folding-blades F, which allows the paper to pass and the tapes T, and over, the bals Q, preventing it from leaving the tapes T, and striking against the blade F, and insuring the folded edge of the paper strik-ing against the stopbar S.

From the rollers B B' and -O 0 pass a like series of pes, T, for conveying the paper out horizontally; d-,abovc said series of tapes are arranged lthe bans. E. to the main framing, arranged as before s'dibedsfor the rst series of tapes, to prevent the M f Vlggyiiviiig the tapes, or striking against the tapes, and holes for they 'as elearly shown in fig. if, thc

blades (l and ll, (sec fig, 2,) and to insure its striking against the respective stopdiars S', (one not shown.)

rlhe blades l? and Il anA operated by the cani 8, as clearly shown in fig. il, and the blade (lr is operated by the cani 1.0, on the spur-wheel of the main shaft, said blade Giv being` held up by a spring (not shown) coiled about its axis. The peculiar moi-'ement of these blades will be more particularly set forth hereafter.

Under the rollers l) 1)', secured to a suitable shaft working in boxes, secured to a swiuging'frznne, is the fly U, which derives itsI upward inotion from the cani 9, on the niain shaft, bcll-erank 1l, and connectingrod 12.

The downward motion of the springr coiled around its l and 2.

lhc swinging frame, carrying the shaft of the y U, is secured to a cross-rail of the main framing by the screw 3, in such a posit-ion that it may swing round, as represented by dotted lines in tig. 2, to receive the folded sheets when issuing from the rollers G C', when so desired, the fiy U beingr represented iu proper. position to receive the folded sheets from the rollers l) D' in Iig. 2.

At right angles to the. shaft of the fly U, working iu suitable bearings, is a. roller, X, with a ratchetwheel ou the end nearest to the ily, said ratchetwheel being ol'icrated by the lever lV and t-ox V, ou the shaft of the fly U.

fly U is given by a shaft, as clearly shown in figs.

Around the roller X, and horizontally along under the machine, and to the other side and'arohnd another roller working in suitable brackets secured to the lower cross-rail of the machine, passes the endless belt 22, in position to rece-ive the folded sheets from the. fly TT, (see figs. 1 and 1.)

When it isydesired to deliver the folded sheets from the rollers C (.l, the endless belt 22, wit-h its accom partying rollers, as well as the ily U, are turned at right angeles to the position shown in fig. 1, and the belts 'l T thrown off the tape-pulley R' and the rollers (l C'. .liie sheet will then he delivered at'tfie third fold.

The main cani-shaft is hungy in suitable bracketii, and derives its motion from the end of the roller B, through the pinion and spur\vlieel,'as clearly shown in fig. 2.

The rollers li B and 1) 1)' receive their motion from a belt running from a. pulley on a counter-shaft running in suitable brackets o n the right-hand side of the main framing, the rollers C G' derivingmotin therefrom by means of bevel-gear.

The rollers A A receive motion from` a b eltpassing over a pulley on the shaft of the roller C, as clearly shown in tig. 1.

The speed ofthe rollers A Aand B B' should be such as to carry the largest sheet the machine is designed to fold, from the first folding-blade E, through the second foldiugfrollers, and to the second stop-bar, (not shown in the drawings.) and to a position proper to receive the third fold during one levolution of the 'main shaft, and inlike manner the rollers C C' and DD' should carry out the folded sheets in another revolution of' the main shaft, so that any number 'of sheets fed suecessivelyto Vthe machine may clear eac'n other in their passage through. l

vThe roller D' is geared from the roller wheels, as shown in figs. 1, 2,' and 9.' A The rollers A, B, and O, have motion communi' cated to them by means of tapes passing under them from their appropriate rollers, which are driven positively, as before described.

Operation.

.The printed sheets f paper having been pegt'orated D by spu`ri as to allow it to be l'olded out.

the psi .tant front-'tbe and said paper heilig' laid on the table Y', with the signature or first page down, and in such position taken from the pile or bank, placed in such position on the table Z Z', and under the blade E, that the pin I will enter one of the perforations. pin 1' is brought to suoli a dista-nce from the pin I by the adjusting screw 1, (see iig. 3,) that it will just enter the second perforation in the/sheet.4 t

The position of the sheet now being under the control of the register-pins I I', the sheet should be brought into such a position that -the blade E will strike it in the line where the first fold is desired by adiusting the register-pins by means of their Vs, and

0 O', and set-screws. baid set-screws operatsgub. stantially as 1 and 2 do, and are-not shown lin the After the position of the first fold has been determined, t-he sheet should be moved by means of the register-pins I I', bar K, and `the adjusting-screw 2, until the line of thel second fold comes directly over the edge of the blade F.

Power now being applied to the counter-shaft, the l blade E is caused to descend by g'ravity,`its motion being regulated by the cam4 6, until its edge strikes the paper, and the fine points 1? P have perforated it, thus preventing any possibility. of .the paper shifting ou the edge of the blade E. l

'.lbc register-pins I I'are withdrawn '-bygiavity, I

their motionbeing regulated by the 'cam 5, and they leave the perforations in tbe'paper at a greaterveloc:

lity than tiiatat 'which 'the-diane-E descends;

The blade E, on its further descent, fol-ees the pa` per between the rolls and A,-e'reasing it at the line at which the points'P P penetate it, the rolls drawing the paper fotf from-,the points.

The blade/E ystoiis just-'before it reaches the point of contact of the'rolls-A A'. A

The continuous motion 'ofthe rolls draws the paper through, on'ce doubled, the tapes T 1 turning -and The bars Q and Q' prevent the paper from donblin g up by the-tiriction-of4 thctapes T, or 'the momentum ot' the paperg" 'Iliebars Q' prevent the paper from' rislng'o' the tapes, striking against the blade F,'cr thereon,.and insure the folded edge striking against the stop-barjS.- 1

The Btop-bar .S"i s` adjusted at such distance from the bladef G as it is' desired to have the third fold dis- The blade F new descends by gravity, its motion being regulated by the-cam .8; untilI the once folded 4sheet is forced between the rollers B B', and carried out by the tapes '1"T running therefrom until its second folded edge strikes against the stop placed at right angles to 'the rollers Gv Q', (not shown 'n the'. drawings.) i

The blade G next descends, and, in likeifrianner, forces the paper through t-he rolleisC Owb'ence it is rried by the tapes T nndr the blade H, and under. .the bar Q, until its third folded edge strikes ,against 'the stopbar S','(see iig.v2.) t

The blade H now descends, forcing. the sheet be tween the rollers'D D', thus folding it a iburtlritiine',

:.lhe tappet V on the-end of the flylshait, operating A single sheet is.

'lhen the.

less apron 22 a'sliort distance in th(l direction of' the arrow, (sce figs. 1 and 2.)

About tile time ot' thc descent ol' 4the blade (i, the

blade E is again ready to make the iirst fold in the next succeeding sheet', which has been rcglstered on thc pins I I during the times they and the blade It remain up, as shownin iig.` 1-.

Should the operator i'ail to get the sheet pointed before thc descent of the blade l1l, its lnotion may be arrested by pressing onthe treadle 21, which throws forward the arm 1.9, so as tocoine across the'path ot' .motionof the projection 18, of the blade-arm 14,

,than where the points on the bladel struck it, thus making inaccuracies in the. first fold.

' The sheet'also would he liable to the blade-at one end before the other, and thus start tbe' sheetl between the rolls at an angle, and bring it sidewise under the second folding-knife F, thereby producing irregularities in the posit-ion of the second fold. A Hence the necessity of tbc' foldingblade E pass,-

ingbetween the rollers A A/ at a velocity equal to or 'greater than that of their periphery.

11 or the same reasons, the blades F', G, and'H, should move at a greater velocity than the periphery of the rollers with which they Operate. v Also, for thereason that', if they moved at a lower reIcity, t-ne" outsdepagesif' the once or'more frequently folded sheetswould be drawn-between the 'rollers in advance of the inside pages, thus causing the folds in the different pages to be-some dist-ance from eachother, and rendering the vsnbsequentfolds inaccurate and unsightly.

. These peculiar mot-ions' 0f the blades are obtained lby the peculiar shape of thc cams operating them,

which are constructed, as a general rule, in combina-I .tion wit-l1 the friction-rollers running thereon, so as to allow the gradual descent of the blades, until near their 'Contact with the paper, and then to permit them to descend rapidly to th'e lowest point of their motion, when they gradually' return to their original position,

as clearly shown in tigsp', 7, .and 8.

The cain '5, operating the register-pins, is lmade still steeperl than the cam 6 operating the blade E, the

etectI being to withdraw the pins, as before specilied.-

will be so deposited thatitsfhead will overlap the previously-depositedsheet, thus -preveuting the pile from becoming so big toiflLpven and yet enabling sheets.
